This invention relates to powder holding and control mechanism and has for its object among other things, to provide a sim ple and effective device for holding powder and controlling itsmovenient therefrom so that it may be discharged in timed relation to other mechanisms with the maximum speed, and also provide a simple, convenient and independent means associated therewith for exhausting the entire contents of the holder.

Having these and other ends in view, my

invention consists in the powder holding and control mechanism, having certain details of construction and combinations of parts as will behereinafter described and more particularly pointed out in the claims. Referring to the drawings, in which like numerals of reference designate like parts in the several figures: I

Figure 1 is a fragmentary sectional elevation of my improved mechanism;

Figure 2 is a fragmentary side elevation thereof looking toward the right of Figure 1 and Figure 8 is aview similar to Figure 1,

with some of the parts in positions different than those shown in Figure 1. My invention is particularly 1 wherein powder is automatically discharged into shells conveniently arranged to receive it. althoughnot limited to such use.

llhe usual method of supplying powder to cartridge shells in such machines provide. a reciprocating slide 'ivhich pletes one full movement for each shell loaded. As sufficient time must be given, not only for the 'reciprocatory movement of the slide, but lso for holding the slide against movement while the charge of powder is being discharged therefrom, the op erations of the machine are thus slowed up because it cannot function faster than the loading mechanism. of mechanism the powder hopper could only be emptied by dismantling the mechanism, an operation both dangerous and time consuming. e

In the mechanism herein disclosed a recipis to com rocating slide is utilized, so constructed and adapted for ass in connection with loading mechanism,

Under this old form bled, as no additional time is required to load and unload the slide, a charge of powder being received while the preceding charge is being unloaded, and vice versa, and the siirplus or excess supply of powder is exhausted or withdrawn with the mini irium incoiwenience' and at practically no risk. v

In the embodiment of my invention there is provided a bracket 10, in which is a chamber 11 and twodivergent discharge passages 12 13 leading therefroiin A conductor 1%, having a chamber 15 therein, which registers with the chamber 11, is secured to the bracket 10 and provides convenient means for guiding powder from a hopper or other source of supply. Tl is' bondiictornmy be. of any length or shapethat is best adapted for the particular form of machine with which it is associated.

The powder in the chambers 15 and 11 passes cownwardly in two streams therefrom through the passages 12 and 13.

lifovab le in the base of the bracket 10 is a slide 16, held against movement in one direction by the cap l7 thatis secured in position by bolts 18 or the like. 'ed in this cap is a fiinnel 19, the smaller end of the ports 12 and 13 Cartridge shells 20 are succe'ssirely moved into register with this funiiel bv arithmetic mechanism or manually, as desiredpthe details of which mechanism are not essential to an understanding" of this invention.

Within the slide are two bushings and 22., each of which has aninverted ope-ning 23 therein, the lz'rrg'Qer end of the opening being adjacent to the bott of the 'de and of substantially the sam diameter the larger end of the openingin the funnel The small ends of the openings tl ough these bushings are of less diameter than that of the passages 12 and 13, These bushings are spacedapart a distance substantially half the distance between the center of the open ends of the passages 12 and Thus when one bushing is in register with the open end of the passage 1" as shown in link 25.

Ve will assume that the parts are in the position shown in Figure 1, at which time the powder in the bushing 22 is passing through the funnel 19 into the cartridge shell thereunder. and the bushing 21 is receiving a new charge of powder from the chamber 11 through the passage 12. At the next stroke of the slide 16, which is toward the left in Figure 1, the bushing 21 is brought into register with the funnel and discharges its charge into a new cartridge, which has been presented thereunder and the bushing 22 is in register with the port 13 and receiving a new charge. These motions are continned and at each forward and return stroke a charge of powder 1s both received and discharged from the slide. As the time necessary to recharge a bushing is no greater than required to discharge the same, there is no. timelost in these operations, the new charge being taken into the slide at the same time that an old charge is being discharged.

To empty the reservoir andexhaust therefrom all of the excess powder therein, it is only necessary to remove the pin 26 connecting the rock arm 24 with the link 25, or the pintle 27 connecting the latter with the slide 16, whichever may seem most desirable, and then move the slide to a position wherein the upper end of the angular port 28 therethrough will register with the port 13. lVhen so positioned, the lower end of port 28 will register with the funnel 19 and the powder from the chambers 11 and 15 will run freely through the passage 13 and port 28 and tunnel 19. If any powder remains in the port 12 it is withdrawn by filling either one of the bushings 21 or 22 and then moving the same into register with the fun nel a sufiicient number of times to exhaust all of such powder.

A slide ,29 having an opening 30 therethrough is mounted in the cap 17, which opening in one of its positions registers with the opening in the funnel 19. When so registered the funnel is open to receive powder from either one of the bushings or from the port 28. By shifting the position of this slide so that the opening 30 is out of register with the funnel, the latter is closed so that the supply of powder from the funnel may be shut off at any time.

A tapping mechanism 31 of any desired type may be utilized to prevent clogging of anyof the parts with powder that does not flow freely. V 7

There are minor changes and alterations that may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not linnt myself to the exact construction herein shown and described, but claim all that falls fairly within the spiritand scope of the appended claims.

What I claim as new and desire to secure by Letters Patent, is

1. In an apparatus of the character described; a reservoir member having a chamber therein and a plurality of divergent dis- 1 charge passages leading therefrom that terminate in openings through an outside wall of said member; a support member having a port therein; a slide movable relatively to the reservoir; a member having openings therein equal in number to said divergent discharge passages; and means for actuating said slide in a substantially straight path, whereby at the end of its movement in one direction one opening in the slide will register with the open end of one of the divergent discharge passages, the other opening will register with the port in the support member, and the open end of the other divergent discharge passage will be closed by the slide, and at the end of the movement of the slide in the opposite direction the opening in the slide last in register with a divergent discharge passage is in register with the port in the support member and the opening therein last in register with the port in the support member is in register with the open end of that divergent discharge passage closed by the slide as aforesaid.

2. In an apparatus of the character described; a reservoir having a plurality of discharge passages; a member movable relatively thereto having the same number of openings therein as there are discharge passages in the reservoir, said openings being conical in shape with the smaller end adjacent to the discharge passages; and a support member for the movable member having a port therein with which the openings in the movable member are successively brought into register, to receive material from the reservoir and discharge the same, through the last mentioned port, at each forward and backward stroke of the movable member.

3. In an apparatus of the character described; a reservoir having a plurality of discharge passages; a member movable relatively thereto having the same number of openings therein as there are discharge passages in the reservoir. said openings being conical in shape with the smaller end adjacent to the discharge passages; and a support member forthe movable member having a port therein with which the openings in the movable member are successively brought into register, to receive material from the reservoir and discharge the same, through the last mentioned port, at each forward and backward stroke of the movable member, the port in the support member being conical in shape with the larger end adjacent to the movable member.

4. In an apparatus of the character described; a reservoir; 21 support member having a port therein; a movable member having a port thereon which in one of its positions will register with one of the discharge passages in the reservoir and the port in the support member, whereby the contents of the reservoir may be discharged from the reservoir through the port in the support member without movement of the movable member.

In testimony whereof, I have hereunto aflixed my signature,
